Outdoor portable energy storage power supply is an important equipment in modern life, and its performance and reliability are very important for outdoor exploration, emergency backup and other scenarios. In order to ensure the quality and safety of such power products, must be based on a series of strictTest standards and methodsMake an assessment. This article will discuss the test standards and methods of outdoor portable energy storage power supply, as well as its importance in ensuring product performance and safety.

1. Test standard

-IEC 62133

IEC 62133 is the International Electrotechnical Commission developed the "portable battery-powered equipment and devices safety requirements and test methods" standard. The standard mainly includes the following aspects of the test:

• Safety of battery cells: Including battery short circuit, overcharge, overdischarge and other tests to ensure that there will be no safety risks under various abnormal use conditions.

• Safety of battery pack: Evaluate the safety performance of the battery pack in the overall device, including the performance under mechanical shock, vibration, temperature changes, etc.

• Electrical Performance: Including the charging performance and discharging performance of the battery pack, the functional evaluation of the battery management system (BMS), etc., to verify that its performance in actual use meets the requirements.

-UN 38.3

The UN 38.3 is a UN test requirement for the transport of dangerous goods. Although it is mainly aimed at the safety of battery transportation, the test items such as vibration, shock, pressure, and temperature cycle are also suitable for evaluating the stability and durability of the battery in actual use.

-UL 2054

UL 2054 is the U. S. safety certification body UL "portable battery-powered equipment safety requirements" standards, covering the battery-powered equipment safety performance assessment, including the battery short circuit, temperature rise, shock, vibration and other tests.

2. Test method

-Battery safety performance test

1. Short circuit test: Under control conditions, perform a short-circuit test on the battery to evaluate its safety performance under short-circuit conditions.

2. Over-charge/over-discharge test: Simulate the reaction of the battery under overcharge or overdischarge to ensure that it will not cause fire or explosion.

3. Temperature cycle test: Under different temperature conditions, perform cycle charge and discharge tests on the battery to evaluate its safety and stability under temperature changes.

-Electrical performance testing

1. Charging performance: Evaluate charging efficiency, charging time, battery temperature changes during charging, etc.

2. discharge performance: Evaluate discharge capacity, discharge time, battery voltage stability during discharge, etc.

3. BMS Functional Test: Verify the protection function of BMS in the process of battery charging and discharging, such as overvoltage protection, undervoltage protection, overcurrent protection, etc.

-Environmental Adaptability Test

1. Vibration test: Evaluate the safety performance of the battery in a vibration environment to avoid damage or failure during transportation or use.

2. Impact test: Evaluate the safety performance of the battery when subjected to external impact to ensure that it will not be damaged by mechanical impact.

3. Temperature/Humidity Test: Simulate battery performance under different temperature and humidity conditions to ensure normal operation under various environmental conditions.

3. Test content

-Battery performance evaluation

Including static and dynamic conditions under the battery capacity test, cycle life test, charge and discharge efficiency test.

-safety performance evaluation

Evaluate the safety performance of the battery under abnormal conditions of use, such as overcharge, overdischarge, short circuit, etc.

-System Integration Test

Evaluate the integrated performance of the entire portable energy storage power system, including the coordination of the charger, inverter, BMS and other components.

4. Test steps

-Preparation phase

Set up the test plan according to the test standard and method, and prepare the test equipment and environment.

-Execution Phase

In accordance with the set test plan, in turn the test, record data and ensure the safety of the test process.

-Data analysis

Analyze the test data, evaluate the performance and safety of the battery, and make adjustments and optimizations based on the analysis results.

-Report Generation

Organize the test results, write a detailed test report, record the test process, data analysis and conclusions, and provide a basis for product quality certification and improvement.

The test standards and methods of outdoor portable energy storage power supply are the key steps to ensure product performance and safety. By testing in strict accordance with international standards, the performance of the battery under various conditions of use can be comprehensively evaluated to ensure its stability and reliability in practical applications. These tests not only help improve product quality, but also enhance consumer trust and satisfaction with products, and promote the wide application and development of portable energy storage power supplies in the market.
